Nepenthes alata is a vigorous growing species from the Phillipines. The taxonomy of the alata affiliated groups was recently redone, leading to the taxa being broken up into a number of species. We're unsure which classification this clone would fall under but my inclination is graciliflora.
This clone originates from Japan and has been in circulation for a couple decades. Variegated Nepenthes are quite rare and this one boasts remarkably stable variegation in the both the leaves and pitchers.
